OK, I've checked it in for you, thanks. Please do contact Chris about write access.

No, I don't.

Hi all, I'm trying to implement llvm.memory.barrier on PowerPC. I've modelled my patch (attached) on the implementation in X86, but when I try and compile my test file (also attached) with llc I get the error "Cannot yet select: 0x10fa4ad0: ch = MemBarrier 0x10fa4828, 0x10fa4c68, 0x10fa4be0, 0x10fa4be0, 0x10fa4be0, 0x10fa4be0". This presumably means my "membarrier"

Hi all, I'm currently implementing a linux/ppc target in llvm. The abis between Darwin/ppc and linux/ppc are different and I'm running into problems with vararg calls. Before a variadic method is called, an extra instruction must be executed (which is creqv 6, 6, 6). This instruction is not necessary in Darwin/ppc. I looked into the PowerPC target implementation and the code generation

Hello all, I've been using Samba for a few years now and have finally come across a problem that I can't seem to sort out myself so I thought I'd use your intelligence instead... Heres the situation. I've got a Linux box (2.4.17) acting as a PDC for some dual boot Linux/NT boxen. Currently users have a single home directory (over NIS to Linux and Samba to Windows) with separate

Nicolas, Would you point me to the Linux/PPC ABI documents you are using so I can better judge what your restrictions are? These changes also have an effect on debugging and exception handling.

This looks OK to check in, do you have write access?

Hi Jim, I didn't use any documents, but intensively looked at gcc's output. I think this document: http://refspecs.freestandards.org/elf/elfspec_ppc.pdf is the last specification of the ABI.

Hi everyone, I have almost completed the implementation of a linux/ppc backend in llvm. There were a few things to modify in lib/Target/PowerPC with a lot of "if (!isDarwin)". There are some places where I need help before saying the port is complete. I attached the diff file as a reference 1) In order to generate a creqv instruction before a vararg call, I created a new

I assume that you did this because PPC is a #define in some system header. Please

I am getting the following error when i am trying to generate the code. In the optimization pass I have inserted some calls llvm.annotation.i32 class to provide indentification tags to loops to be used in subsequent passes. Codegen is complaining about these annotations. llc -march=c ham1_seq.bc3 Error: Code generator does not support intrinsic function 'llvm.annotation.i32'! llc

Meaning one LLVM compiler cannot generate both
